STEPHEN S. NEWTON, OF BINGHAMTON, NEW YORK.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 279,418, dated June 12, 1883.

Application filed April 20, 1882. (No model.)

of New York, have invented certain new and useful Improvements'in Bottle-Stoppers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 isavertical section of my improved stopper with the discharge-port open. Fig. 2 is a similar View with the discharge-port closed. Fig. 3 shows a modified form of the discharge-tube. Fig. 4 is a detached view of the rising and falling ring.

Referring to Figs. 1 and 2, A is the lower part and A the upper part of a dischargetube, the part A being screw-threaded externally and made flaring, as at a, its upper end being closed by a plate, B. l

a is adischarge-port,of which there are preferably two or more.

C is a flange projecting horizontally from the discharge-tube and adapted to cover the tubeeork and neck of the bottle.

D is an internally-threaded ring engaging with the external thread of the discharge-tube, and provided with a milled ring, 01, and with a flange, d, made flaring to fit closely the under side of the flanged portion a of the dischargetube. r From an examination of Figs. 1, 2, and 4, it will be readily seen that when the ring is screwed down, as in Fig. 1, the contents of the bottle can be readily discharged through the port or ports a, and that when the ring is screwed up, as in Fig. 2, it closes the discharge port or ports; and it will also be seen that the flange a fits closely the flange d, so that no dust will enter between these flanges.

In Fig. 3, I have shown a form of dischargetube, E, having an external screw --thread throughout its entire length below the flange a, so that the ring can be conveniently screwed onto the tube, and whereby the tube is alsoadapted to receive a cork, F.

In the construction shown in Figs. 1 and 2 the cap-plate B may be made separately from the discharge-tube, the flange a being formed .by spinning after the ring D has been placed the flaring flange a after the ring. has been placed on the tube, and then by forming the rising and falling ring with a correspondinglyflaring flange at its upper edge I am enabled to form a throat through which to discharge the contents of the bottle, the sharp upper edge of the ring practically preventing file liquid from dripping down upon the outside of the ring. So, also, there is formed a conduit between the outer and inner threads, whichserves to conduct back into the port such liquid as may remain in the groove between the flange d and the discharge-tube, thus effectually preventing any portion of the liquid from being squeezed out from between the flanges ad when the ring is screwed up to close the port or ports, the port extending to the base of the flange a. Thus this construction of stopper is specially adapted for use with liquids which are somewhat viscid, such adaptation being due to the peculiar construction and combination of parts shown.

While I am aware that a bottle-stopper having a lateral port in its discharge-tube, which port is opened and closed by a sliding ring, is old, and I do not therefore claim such construction, broadly, yet I believe that my construction possesses many advantages over those heretofore known.

What I claim is In a bottle-stopper, an externallyscrewthreaded discharging-tube provided at its upper end with a lateral port, and with aflaring flange, a, and a closing-plate, B, in combination with a rising and falling screw-threaded ring, D, provided at its upper end with a flar ing flange, cl, substantially as set forth.

In testimony whereof I affiX my signaturein presence of two witnesses.
